0852 Stop flashing the detector.
0914 Fill N2 cold trap full
1125 Start to take data 07110319_1125_F0001. 2000 random triggers. -6V on Q1, 0V on Q2-4. Trigger, 64ADC on Q1. Ba-133 source. Tower: 63.4mK
Stop the because the trigger didn't seem to happen at the right place.
Resynchronize the two boards.
1130 start the run 07110319_1130_F0001. 2000 random triggers. -6V on Q1, 0V on Q2-4. Trigger, 64ADC on Q1. Ba-133 source. Tower: 63.4mK
1134 The trigger worked OK now. The random trigger was set to 2000 instead of 500.
1624 Stop the run at 07110319_1130_F0014. Flash the detector.
1837 Stop flashing
1924 Start take data 07110319_1924. 500 random triggers. -4V on Q1, 0V on Q2-4. Trigger, 40ADC on Q1. Ba-133 source.
2214 Stop the run 07110319_1924 at 9th file. I feel kind of suffocated staying in the lab with ventilation off. I think the reason why we could not see Am/Ba peaks is because there are too many pileup events. Shortening the trace length may be able to fix this.
2217 Flash the detector.
